Turntable Mats: Rubber, Felt or Cork.


I have a Linn Basik Turntable with an Akito tonearm and Rega Exacta 2 cartridge. Would one expect a noticeable sonic difference when changing from a felt mat to a rubber and cork mat?

I tried a bunch of different mats, but held onto my achromat and Herbies way excellent mat. 
Quick question for Noromance.

Would you consider the PAC oversized platter an essential upgrade for the 401?
Mine has stock platter on it still.
What would you say it brought to the table.( Sic).
Thanks
Some proper mats as alternative to any modern mats:

my CU-180 with ST-10 and SAEC SS-300

Two best vintage mats on the market, the last one is much cheaper.

Instead of isolation platform under a turntable i would recommend to use pneumatic feet (support up to 60kg).
